⚠️ If you are looking for the Booking.com connection guide, see Connect a Booking.com Listing to Hospitable.
⚠️ If your main problem is duplicates / multiple “rooms” imported from Booking.com, see Booking.com Listings With Multiple Rooms and Multi-Room Reservations.
If you are trying to connect Booking.com to Hospitable and it keeps failing, this guide helps you identify the most common blockers and fix them.
⚠️ Start The Connection on Hospitable (Important)
You must start the connection from Hospitable, not from Booking.com.
In Hospitable, go to:
Channel connections →
Connect with Booking.com
and begin the flow from there.
If you started from Booking.com, the connection may get stuck in a “pending” state (see Confirm a pending connection below).
See the full Booking.com connection guide here.
Before Troubleshooting: Confirm These Requirements
Most connection failures happen because one of these prerequisites is not met.
1) Your property must be Open / Bookable on Booking.com
Your Booking.com property status must be Open/Bookable before connecting. If it is snoozed or temporarily closed, reopen it in the Booking.com extranet first.
2) You need at least one active rate plan
Hospitable requires at least one active rate plan on Booking.com. If there is no rate plan, the connection can fail (and rates and availability cannot sync).
See how to create a rate plan on Booking.com here.
3) Remove iCal imports and disconnect other PMS connections
Booking.com only allows one connectivity method at a time.
Before connecting, do both of the following in Booking.com:
Remove any imported iCal calendars
Go to your Booking.com Extranet
Select the property in question
Go to Rates & Availability or Calendar & Pricing
Select Calendar sync
If you see any connected iCals there, please delete them
Disconnect any existing connectivity provider (PMS, channel manager, pricing tool)
Go to your Booking.com Extranet
Select Account
Select Connectivity provider
Click Disconnect if there is any connected software there
⚠️ Important: removing iCal links can temporarily make previously blocked dates bookable. Complete the Hospitable connection as soon as you remove them.
4) “Rooms to sell” must be 1
If your listing is set up like a hotel or multi-inventory property (rooms to sell greater than 1), Hospitable cannot connect it. Update the inventory so Rooms to sell = 1 on Booking.com.
Fix the most common connection problems
A) “There is no pending connection request for this listing ID” (or similar)
This usually means the pending connection flow was not completed, or the connection was started on Booking.com rather than in Hospitable.
Fix: Confirm a pending connection
In Hospitable, go to Channel connections → Connect with Booking.com
Click I already have a pending connection with Hospitable
Continue the flow and enter:
the Booking.com account email
the listing’s Accommodation ID
Keep the Hospitable window open until the connection finishes loading (this can take a few minutes).
See the full connection flow here.
B) “Accommodation ID not found” (or the listing does not appear)
Double-check that the Accommodation ID you entered matches the exact listing you want to connect. The Accommodation ID is shown in the Booking.com extranet near the property name.
If the ID is correct and it still cannot be found, check again for:
iCal imports still present
Another connectivity provider still connected
Either can prevent Booking.com from accepting the connection request.
C) Connection fails, and you use another tool (PMS, channel manager, pricing)
If your Booking.com listing is connected to any other software (PMS, channel manager, pricing tool acting as a connectivity provider), Hospitable cannot connect until that provider is disconnected in Booking.com.
After disconnecting the other provider, retry the Hospitable connection flow from the start.
D) You added new listings in Booking.com and expected them to import automatically
New Booking.com listings added directly in Booking.com do not automatically appear in Hospitable. You must connect each additional listing from Channel connections → Connect with Booking.com and enter each Accommodation ID.

FAQ
Do I need to start the connection in Hospitable or Booking.com?
Start in Hospitable. Starting on Booking.com can lead to a stuck “pending connection” state.
Can I connect if I have imported iCal calendars on Booking.com?
No. Remove all iCal imports first, then connect through Hospitable. Be careful because removing iCal links can temporarily make blocked dates bookable.
Why do I need a rate plan?
Hospitable requires at least one active Booking.com rate plan to connect and sync rates and availability. If there is no active rate plan, the connection can fail.
See how to create a rate plan on Booking.com here.
What does “pending connection” mean?
It means Booking.com is expecting a connection confirmation that was started but not completed (for example, you closed a window mid-flow or started on Booking.com). Use I already have a pending connection with Hospitable in the Hospitable connection flow.
My listing has “Rooms to sell” greater than 1. Can I connect?
Not currently. Hospitable does not support multi-inventory or hotel-style setups. “Rooms to sell” needs to be 1.
I connected, but my Booking.com listing looks blocked. Is that expected?
It can be. Hospitable may temporarily close the calendar while syncing. If it stays unpublished, publish it from Hospitable (see the publishing guide here).
Do upcoming reservations import when I connect?
Yes, ongoing and upcoming reservations import. Past reservations (with checkout dates already in the past) do not import due to Booking.com API limitations.
Read more about importing reservations from Booking.com here.
Can I message guests immediately after connecting?
Not immediately. There is a 48-hour window after first connection where manual messages cannot be sent from Hospitable to Booking.com guests.
